I think that’s the reason why I got the full version although I admit I never use the C4 remote UI to browse media. I just prefer browsing on my 154" screen lol. It does work but if I recall correctly it didn’t show the coverart on remote. Chowmain support advised that I had to disable username/password on Kodi web server for cover art to work but I didn’t bother.
An FYI, for those who might want something else. Another choice for controlling from an IOS device is TouchControl. I use it to control my lighting, AVR, Vero, Apple TV, various smart switches like to turn on my subs, my projector, BluRay player, etc. This software is mostly for those who can do some programming as most things you have to make work yourself. But it’s extremely flexible. Knledge of javascript (some) helpful.
